True progress happens when we dare to question the status quo.
The best ideas come when you’re not looking for them.
你做得越多，学到的就越多。你学到的越多，你能做的就越多。
Having less is more; contentment leads to happiness.
The healthy social life is found when in the mirror of each human soul the whole community finds its reflection, and when in the community the virtue of each one is living.
